14.6 Properties

Topic Version1Published09/11/2015
For StandardRESQML v2.0.1

Individual property values are attached to a single type of element in the representation, either its topological elements, such as nodes or cells, or larger elements such as the entire representation or large parts of it, through patches and sub-representations.

Each property value is also associated with a single property type, which provides global semantics about the meaning of these values. Property values can also be associated with facets, which provide additional context for the values.

It is very common in subsurface/earth modeling workflows to follow the evolution of some property values through time or to consider them together as a group of property values attached to the same or different representations and property types. To capture this information, RESQML provides the notion of time series and a property group.

When spatial locations (geometry) need to be stored for specific elements in a representation, then property points are used.

NOTE: The. To specify a UOM not in the Energistics UOM standard, specify the property’s UOM as "Euc" (a place holder value). Then use ExtraMetadata, which is a top-level object component, to specify "Uom" as the Name, and the UOM symbol (such as "barns/electron" or "s1/2") as the Value.
